Test 2 will be Thursday, April 3 in class. It will be closed book and notes, except for one 8.5” x
11” sheet of paper (front and back) with notes and the green MARIE Assembly Language
handout. (NOTE: NO MIPS material on this test!!!)
Chapter 4.
Functionality of Computer Components: CPU, Bus, Memory, Clocks, I/O subsystems, Interrupts
CPU Basics: Fetch-Decode-Execute machine cycle, datapath including ALU and registers,
control unit
Clocks: frequency, relationship to program performance
MARIE: Architecture, Instr. Set Architecture, machine language format, RTN/RTL for
instructions, Fetch-Decode-Execute cycle, I/O
Assembly Process: two-passes, symbol table, assembler directives
MARIE Hardwired Control Unit
MARIE Microprogrammed Control Unit
Tradeoffs between Hardwired vs. Microprogrammed Control Units
You should be able to:
write a sequence of RTN/RTL for any MARIE instruction or any new MARIE instruction
that we might want to add
translate a segment of high-level language code to MARIE assembly language. (like HW #4)
partially implement the hardwired control unit for MARIE (like HW #5), and
write some microcode for the microprogrammed control unit. (like HW #5)
